Hierarchical zinc oxide nanorings with superior sensing properties

ZnO nanoleaves with superior photodetection properties

“…Hierarchically nanostructured ZnO with onedimensional (1D) or two-dimensional (2D) building blocks have drawn a great deal of attention recently due to their astonishing physical and chemical properties. [30][31][32][33][34][35] More specifically, such structures have already been demonstrated to be applicable in the bottom-up production of high-performance devices. [5][6][7][8][30][31][32][33][34][35] With these systems in mind, we herein report the development of an elegant nucleation and growth strategy to synthesise hierarchical ZnO nanoleaves (ZNLs) and nanoflakes (ZNFs) from initial monomorphological ZnO nanostructures, ZnO nanowires (ZNWs), and ZnO nanodiscs (ZNDs), respectively.…”

This growth strategy allows us to control and optimize the experimental conditions stage by stage and gives a chance to rationally design and synthesize the morphology of nanostructures.…”

On-substrate fabrication of a self-activated nanostructured ZnO gas sensor

“…Subsequently, the chemical reactions at the surface of the nanostructure between gas molecules and oxygen ions transfer charges between the surface and the bulk, changing the electrical conductivity of the nanostructure. [10][11][12][13][14][15][16][17][18] Despite the numerous advantages of metal oxide nanostructured gas sensors, it is still challenging and dangerous to sense gases with sensors that are thermally activated. Thermally activated gas sensors would be bulky and energy consuming requiring additional components that are difficult to…”
